Description
Technical field
The present invention relates to coal slime flotation auxiliary agent, the promoter that especially coal slime flotation is used.
Background technology
Flotation is the main method that coal slime reclaims, and it is the difference that relies on coal and spoil surface nature, in gas-solid-liquid three-phase, carries out sorting.Coal slime flotation process need to add non-polar hydrocarbon oil (as kerosene, diesel oil) to improve coal grain surface hydrophobic as collecting agent conventionally.Oil does not dissolve in water for coal (bavin), bad dispersibility in water, can only be with large " oil droplet " form existence (>1mm), to come in contact the probability that collides and adhere to less with coal grain, also can be gathered into larger oil droplet simultaneously, therefore, the oily consumption of coal (bavin) is higher.In addition kerosene and diesel oil are many from petroleum cracking product, along with rise of the oil price, cause coal separation cost to rise, and have reduced coal separation economic benefit.
In order to improve the dispersibility of coal (bavin) wet goods hydrocarbon ils collecting agent in water, generally by adding promoter (being generally surfactant) to improve its collecting effect.Current universally recognized principle is: reduced on the one hand the surface tension of oil-water, improved the dispersiveness of coal (bavin) oil, it is dispersed in ore pulp with more tiny " oil droplet "; On the other hand, promoter also can become hydrophobic by coal surface local hydrophilic region, improves the surface hydrophobic of coal grain integral body by surface modification.But in fact, promoter not only can be by coal surface modification, equally also can be by spoil surface modification, so just cause in actual floatation process, although promoter can be reduced the consumption of coal (bavin) oil and be obtained higher clean coal yield, but also inevitably part spoil is brought in head coal product, caused cleans ash higher, greatly affected head coal product quality.
APES is a kind of nonionic surface active agent, by those skilled in the art, generally as Promoters For Fine Coal Floatation, to account for the ratio of the oily 5%-20% of coal (bavin), used at present, feature due to its surfactant, also inevitably there is the non-selectivity surface modification to spoil, cause cleans ash generally higher.In order to overcome APES as the defect of Promoters For Fine Coal Floatation, the measure of taking is at present generally that APES is carried out to modification, method of modifying is: take APES as raw material, select suitable sulfur acidizing reagent-sulfamic acid and catalyst, under high-temperature and high-pressure conditions, carry out esterification, obtain having concurrently the APES derivative of non-ionic surface active agent and anion surfactant advantage--APES sulfate, or after finishing, reaction further neutralizes with NaOH, obtain alkyl phenol polyethenoxy ether sodium sulfate.Preparation method such as the disclosed a kind of alkyl phenol polyethenoxy ether sodium sulfate of China Patent Publication No. CN101328141A, it take APES and sulfamic acid is raw material, at the carbamide compounds that has alkyl or aryl to replace, carry out esterification under as the condition of catalyst, APES, the mol ratio of sulfamic acid and catalyst is 1: 1～1.2: 0.1, esterification reaction temperature is 110～130 ℃, 60～120 minutes reaction time.Esterification finishes in rear use NaOH and esterification reaction product APES ammonium sulfate, finally obtains product alkyl phenol polyethenoxy ether sodium sulfate.
The defect that said method exists is: when APES is carried out to modification, those skilled in the art have only considered the conversion ratio of APES, in order to improve the conversion ratio of APES, the artificial reaction temperature that improves, extend the reaction time, and utilize catalyst to promote reaction, finally obtain alkyl phenol polyethenoxy ether sodium sulfate.Alkyl phenol polyethenoxy ether sodium sulfate is anionic surfactant, electronegative in ore pulp, repel mutually with electronegative spoil particle surface, the intensity of adsorbing post-modification at spoil particle surface, much smaller than APES, is conducive to improve the non-selectivity collecting to spoil in floatation process.But alkyl phenol polyethenoxy ether sodium sulfate is compared with APES, the general high 3-4 of critical micelle concentration (CMC) doubly, the efficiency that the critical micelle concentration increasing substantially (CMC) causes alkyl phenol polyethenoxy ether sodium sulfate to reduce oil-water surface tension sharply reduces, and is unfavorable for improving the dispersed of coal (bavin) oil and saves its consumption; In addition, in order to pursue a series of technical measures that high conversion takes, make synthetic cost high, synthesis technique is complicated.
Summary of the invention
In order to overcome APES promoter simultaneously, easily cause cleans ash higher, greatly affect head coal product quality, and the synthetic technological deficiency that cost is high, synthesis procedure is complicated, the dispersion effect to hydrocarbon-type oil when coal slurry flotation is poor, hydrocarbon-type oil collector dosage is large of alkyl phenol polyethenoxy ether sodium sulfate promoter, retain the two advantage simultaneously, the invention provides a kind of preparation method of Promoters For Fine Coal Floatation.
The present invention provides the method for coal slurry flotation simultaneously.
For achieving the above object, the preparation method of Promoters For Fine Coal Floatation of the present invention is: take APES (degree of polymerization of ethylene oxide is n=4-12) and sulfamic acid is raw material, both mol ratios are between 1:0.5～1:0.6, controlling reaction temperature is 70～90 ℃, in building-up process, need to constantly stir, reaction time is 30～40 minutes, after reaction finishes, be down to normal temperature, the conversion ratio of APES is generally 40～50%, the product obtaining after reaction finishes comprises APES and synthetic APES ammonium sulfate, and the molar ratio with 1.5:1～1:1 coexists.
The method of coal slurry flotation of the present invention is:
The first step: prepare according to the method described above promoter
Second step: two agitators are set, are called one section of agitator and two sections of agitators, one section of agitator is arranged in a high position, and two sections of agitators are arranged in low level, ore pulp can enter two sections of agitators from one section of agitator gravity flow.
The 3rd step: the black water coming from separation system is introduced into one section of agitator, then to the promoter that adds the first step to prepare in one section of agitator, requiring the addition of promoter is 2～24g/t delivering dry coal slurry, guarantees the 1 minute above time that stirs and evenly mixs, mixer rotating speed 2000～2800r/min;
The 4th step: the black water that the 3rd step is mixed to promoter flows automatically to two sections of agitators, at two sections of agitators, add hydrocarbon-type oil collecting agent and foaming agent simultaneously, guarantee the 1 minute above time that stirs and evenly mixs, requiring the addition of hydro carbons oils collecting agent is 0.4～1.2kg/t delivering dry coal slurry, foaming agent consumption is 0.04～0.12kg/t delivering dry coal slurry, mixer rotating speed 2000～2800r/min;
The 5th step: the mixture that the 4th step is formed enters flotation device and carries out flotation.
The mechanism of action of promoter of the present invention is:
Promoter of the present invention has two kinds of compositions, respectively APES and APES ammonium sulfate, with mol ratio 1.5:1～1:1 composition of proportions, these two kinds of compositions are by synergy, the critical micelle concentration (CMC) that can make promoter is lower than APES and the APES ammonium sulfate critical micelle concentration of independent system (CMC) separately, the efficient oil-water interfacial tension that reduces, greatly improve the dispersiveness of hydrocarbon ils in water, form tiny " oil droplet " (1 * 10
-3～0.5mm), significantly reduce the consumption of hydrocarbon-type oil collecting agent; In addition, by the repulsive interaction between APES ammonium sulfate and electronegative spoil particle, reduced the in use non-selectivity collecting effect to spoil of promoter of the present invention.
The following describes advantage of the present invention:
In general knowledge known in this field, after APES modification, there is the collecting ability that improves collecting agent, the conversion ratio of modifying process Raw is higher, the product obtaining is purer, active constituent content is more, the amount of using during coal slurry flotation will reduce, this not still those skilled in the art be also the cognition in other field, based on this Traditional Thinking constraint, those skilled in the art are when carrying out modification to APES in guiding, idea manages to improve the conversion ratio of APES, in order to improve the conversion ratio of APES, do not stint raising reaction temperature, reaction time and pressure, nobody goes to think otherwise possibility.The inventor has overcome this technology prejudice, propose a kind of and conventional art and conceived diverse technical scheme, courageously reduce APES modification temperature and time, thereby reduce the conversion ratio of APES, make in the composition system after modification, APES and APES ammonium sulfate are in a best proportioning of improving collecting agent collecting performance the most applicable, under best conditions of mixture ratios, APES is far longer than to the synergy of APES ammonium sulfate the defect that itself may bring, thereby obtain lowest surface tension under critical micelle concentration, reach efficient reduction oil-water interfacial tension, improve the dispersiveness of hydrocarbon ils in water.And the cost of promoter and coal slime flotation is reduced greatly, in addition, has also removed operating personnel from and will add the program of a plurality of surfactants when coal slurry flotation, can large-scale application in industrial production.
